Laws

What is a "Scientific Law"?

• A broad field of study focused on nature

• A well-tested and widely accepted description of observations

• Physical or mathematical representation of a structure

• A process of scientists reporting the details of their methods

What is Newton's First Law of Motion?

• An object in motion stays in motion unless acted upon by an external force

• Force equals mass times acceleration

• For every action, there is an equal and opposite reaction

• Energy cannot be created or destroyed

Which law explains why we need to wear seatbelts?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Law of Conservation of Energy

What does the Law of Conservation of Mass state?

• Mass can be created and destroyed

• Mass is constant in a closed system

• Mass is the same as energy

• Mass is proportional to volume
